The wheel 16 is journaled on an axle 18 supported in bearings 19 in a yoke 20 having an upright stem 21 journaled in a bearing 22 on the main frame, a pull-yoke 23v being looped about the axle 18. A suitable pulling-agency may be hitched to this pullyoke for moving the machine from place to place. The wheels 17 are mounted on an axle 24 movable up and down in' slots 25 of bearings 26 and cushioned `by springs 27 in sockets 28, set-screws29 threaded in said bearing being arranged to impinge polygonal portions 24 of the axle 24 for rigidly positioning the main frame with relation to the axle during operation of the machine.

31 is a drive-shaft journaled in a bearing 32 of the main frame.I This drive-shaft is -driven in suitable manner and is shown as the crank-shaft of an internaljcombustion motor, the crank 33 thereof being operated in well-known manner from the internal combustion motor 34.

41 isa mandrel arranged to support a suitablewood-cutting agency, primarily a circular sawblade 42. This mandrel is arranged to be angularly adjusted in a vcrti-V iio l cal plane and also in a horizontal plane, and

tight box 73.

is arranged to be adjusted into various tilted positions with relationto both said planes. Driving means are provided therefor in such manner as to maintain driving relation between the drive-shaft and the mandrel throughout the various adjust-ments of the latter, the latter being so arranged also as to permit adjustment of a stock-supporting table located adjacent to said saw-blade.

45 is a table-saddle pivoted upon the main frame and arranged to be adjusted in a horizontal plane. The saw-mandrel is arranged to be moved with the table-saddle in this last-named adjustment.

46 is a table movable back and forth on the table-saddle on guide-ways 47, and held in line by a rib 48 on the saddle received in a groove 50 on the frame of the table.

51 is a bevel-gear on the drive-shaft 31.

52 is f trunnion-sleeve fixed in a bearing 53 on the table-saddle and journaled 'in ay bearing 54 in the main frame.

55 isan upright shaft-journaled in the trunnion-sleeve. It has, a bevel-gear 56 fast thereon at its lower end meshing with the bevel-gear 51 and a bevel-gear' 57 fast thereon at its upper end.

58, 59, are bearings on the table-saddle.

60 is a mandrel-housing having a bea-ringsleeve 61 journaled in the bearings 58.

62 is a shaft journaled .in the bearingsleeve. This shaft has a bevel-gear 63 fast thereon which meshes with the bevel-gear 57 and a bevel-gear 64 fast thereon which meshes with a bevel-gear 65 fast on the mandrel 41, the mandrel being journaled in bearings66, 67, on said housing.

68 is a-rock-shaft journaledfin the bearing 59 and secured as by a pin 69 to the mandrelhousing 60 for rocking the mandrel-housing and adjusting the saw-mandrel into suitable angular position in a vertical plane with relation to the surface 70 of the table.

The bevel-gears 51 and 56 are mounted in an oil-tight box 71, the bevel-gears 57 and 63 are mounted in an oil-tight box 72, and the bevel-gears 64 and 65 aremounted in an oil- When the saw-mandrel is adjusted in a vertiel plane it is desirable that the table be also adjusted toward and from the sawblade so as to maintain close proximity of the, table with relation to the saw-blade. I

provide adjusting means whereby simultaneous adjustment is imparted to the mandrel and the table. 75 is a segment-arm rigidly secured to the rock-shaft 68. It is moved by a handle 76 and clamped by' a clamp-screw 77 having threaded connection 78 with the saddle, `passing` through an arc-slot 79 in'sai'd segmentarm.

When now the segment-arm 7 5*'is rocked, it rocks the mandrel-housing, which through the medium of t-he link 85 and bell-crank lever 82, slides the table-frame back and forth in unison with the rocking adjustment.

imparted to the mandrel-housing, thereby maintaining the proper relative positions between the saw-blade and table throughout the various adjustments of the parts. After adjustment of the parts, the segment-arm is clamped to the'saddle, thereby simultaneously locking t-he mandrel-housing in its angular position and the table-frame in its shifted position upon the saddle.

For adjusting the saw-mandrel in a horizontal plane, the saddle 45 is swung aboutits pivot formed by the trunnion-sleeve 52, the

gears 64 and 65 is also maintained.

The table is provided with a slot 101 extending at right angles-to the axis of rotation of the saw-mandrel. The slide-piece 102 of a saw-fence 103 is received and slidable in this slot. The end of the timber or board to be cut is supported on this table and moved by the saw-fence when it is desired to cut` the same.

An auxiliary table is provided for supporting the overhanging end of the timber f or board, this latter table being preferably mounted on rollers and movable on a track v'arranged to be adjusted parallel to the slot 101. Thus 105 is an auxiliary tableprovi'ded with rollers 106 movable on 'guide-ways 107 on a table-support 108 having an upright trunnion 109 in a bearing 110 in the main frame.. There is a scale 11'1 between the auxiliary table and the table-support. There is further a sca-le 112 between the table-saddle 45 and lthe main frame so arranged that the main and vauxiliary tables are conveniently adjusted to .similar angles. There is further a scale 113 between the arm 75 and the main table 'parts for determining the angle tical plane.

the main table 46, shown by the overhangin provided between ing the saw-blade and cutter-head and preventing interference between t'ne saw-manber -forined on a timber of the character stated drel and the supplemental table, when the4 saw-mandrel is adjusted in a .vertical plane, I provide interchangeable stems 123, 124, on which the saw-blade and cutter-head are respectively mounted, the stems forming part of the mandrel and being received through a bore 125 therethrough and clamped in place by a clamp-nut 126. n

The mandrel may be adjusted in a vertical plane or in a'horizontal plane or in both said planes for presenting the cutting agency at various angles to the' timber. Means are also provided for edging gp the timber by means of thecutter-head, and I have further provided means forbo-ring holes in the timso that the various operations to be permay be performed on this combined machine.

' by means ,of a pinion 141 on a sha-ft 142l The drive-shaft has a sleeve 131 rpceived thereabout, the sleeve having spline-connection 132with said shaft, and being slidable lengthwise in a bearing 133 on the main frame. rIhe sleeve has a socket 134-at its outer end, in which aboring-bit 135 is arranged to be secured. 136 is a table on which the timber is arranged to be placed against bars 137. 138 is an upright post having rack-teeth 139 formed thereon, the post having -the table 136 secured thereto'.

The post is slidable up and down in a bearing 140 of the main frame, and'is moved journaled in a bearing 143 on the main frame and havingfan arm 144 secured there? to. 145 is a plate provided with apertures 146 with whichf a pull-pin 147 on the arm 144 is adapted to ccperate for positioning the height of the table 136. 151 is a bellcrank lever pivoted at 152 0n a bracket 153 extending from the plate 145. 154 is a pin on the bell-crank lever received in an annular slot 155 of the sleeve 131. 156 is an operating lever pivoted at 157 to the plate 145 and articulated at its inner end to the bell-crank lever 151, this latter articulation being shown as a slot 158 on the operating lever in .which a pin 159 on the bell-crank lever is received. The operation of the j' operating lever moves the sleeve 131 and the boring-bit secured thereto in and out with relation to the lstock supported on the table 136, the position of the hole bored in this stock being determined by the height of said.

table and the position of the stock length wise thereof. Y

161 is a starting handle for the shaft of ythe internal combustion motor, and i's pro-l vided with usual fthrow-out mechanism having an inclined bottom, the slotbeing in a crank-extension 164 of the drive-shaft and the handle located on said extension. rlhe drive-shaft has a crank-disk 165 secured thereto on which. a crank-pin 166 is located,

lated at 173 with a pitman 174 having rev ciprocation in a' bearing 175 on the saddle 45, the bearing 17 5 being releasable.

- 176is a resilient arm extending from a block 177 releasably secured to the table by a clamp 178, the block having a rib 179 thereon received in the slot 101 in the tabletop.

v l1180 is a scroll-saw blade suitably secured between the pitman 174i and the resilient or scroll-saw arm 176, the scroll-saw blade passing through the opening 181 in the tableto i iinstancing an operation of my improved device for cutting the b evels at the ends of rafters, employed in constructing so-called hip-roofs, I have illustrated a rater of this kind at 185 in Figs. 15 and 16. The rafter is provided with a bevel 186 extending crosswise of its width and with a bevel 187 extending crosswise of its thickness. The bevel 186 is arranged to compensatevfor the upwardly sloping position of the rafter with relation to the -stringer to which it is secured, andthe bevel l187 is arranged to compensate 'for the angular position of the Stringer crosswise of the roof. the two bevels forming a compound bevel.- For cutting the bevel 186 the saw-mandrel is swung sidewardly for presenting the axis of rotation of the mandrel at an angle in a horizontal plane to the axis of rotation of the drive-v shaft. This is accomplished by manipulation of7 thearm 75. l, When cutting the timber for this purpose it is laid crosswise upon the main table`r and upon the auxiliary table, which latter has also been adjusted to angu- Vshown as a pin 162 received in a slot 163.

pushed crosswise of the table by means of lar position, the timber being positioned It is then the saw-fence, this movelnent also causing the timber to move lengthwise of a driveshaft, for feeding the endrof the board through the saw-blade and prpviding it with the compound bevelstated. The same timbers may also have their edges planed'by the cutter-head, and provided with holes and slots by means of the boring-bit and scrollsaw.

It is of course obvious thato-ther cutting operations. may be performed on the machine.

Having thus fully described my invention, what I claimas new and desire to secure by Letters Patent, is:
